When farmers consume much of their grain output, end-use quality, in addition to standard production characteristics, affects farmers' seed choice and the economic returns to investment in crop breeding. Evidence from Malawi suggests that despite a lengthy research lag, emphasizing grain quality...

Use of soil amendments, including organic materials and mineral fertilizers, is highly recommended for the replenishment of soil nutrients, improved soil health and more efficient use of fertilizers in sub-Saharan Africa. Along with other constraints, underdeveloped markets are often cited as a...

Women are central to food production and maize is a dominant food staple in Sub-Saharan Africa, but published gender analyses of hybrid seed use in Sub-Saharan Africa are uncommon. Building on previous work, this paper tests the effects of headship definitions on hybrid seed use and explores the...
